When a 22-year-old man detonated a bomb at a pop concert at Manchester Arena packed with young women and girls, 9news.com.au was there to deliver the story as it broke.

Salman Abedi's attack on the Ariana Grande concert in May saw 22 killed and countless more injured, and also shook the United Kingdom to its core.

While reports focused on Abedi and details of the bombing, it also produced heartwrenching stories of young fans who had perished at one of the last places people would expect an attack of this nature.

In an award-winning story by nine.com.au reporter Emily McPherson, a Victorian mother revealed how her 15-year-old daughter committed suicide after a year of schoolyard bullying culminating in her gang rape.

What started for Cassidy Trevan as verbal insults on social media escalated into an orchestrated act of rape carried out by two boys, another who stood guard and two girls who organised the crime.

The case was dropped because of a lack of evidence, but her mother Linda shared her story to tell the bullies "it's not just a game... it costs lives."

In one of his great final acts in a career spanning decades, Nine's veteran political editor Laurie Oakes caught Prime Minister Malcom Turnbull in a tremendous gaffe poking fun at US President Donald Trump.

While the PM's address to the annual Mid Winter Ball is traditionally off the record, Oakes made Mr Turnbull's shot at Mr Trump public by sharing it on 9news.com.au.

The leaked audio sent Canberra into a spin, and confirmed Oakes' place at the top of the political media pyramid once and for all.

Just as one infamous drug mule was set free from a foreign prison, Cassie Sainsbury made headlines around the world when she was caught at Bogota Airport allegedly trying to smuggle cocaine out of Colombia.

While her arrest and initial court appearances had been comprehensively covered, a major investigation by 9NEWS and 60 Minutes unearthed claims the Adelaide woman worked at a second brothel in Sydney and deceived friends to her own financial advantage.

The bombshell revelations helped to piece together missing links in Sainsbury's somewhat patchy back story - specifically who she had been mixing with in the months before she was arrested and how she came to be in Colombia.

In another story from nine.com.au's award-winning reporter Emily McPherson, it was revealed an Adelaide woman had escaped jail despite pleading guilty to the aggravated assault of her eight-month-old daughter.

A court heard how Lorien Norman called police in October 2016 threatening to throw Evie off the balcony, but when police arrived to find bruises on the baby's face she told authorities she had fallen at a play gym.

The court's decision sparked outrage from the community, with Father Shane McMahon leading the charge to have the incident brought to justice.
